J-PLUSwww.J-PLUS.es is conducted by the Observatorio Astrofísico de Javalambre (OAJ, Teruel, Spain; [1]}). It uses the 83 cm Javalambre Auxiliary Survey Telescope (JAST80) and T80Cam, a panoramic camera of 9.2k \(\times \)  9.2k pixels that provides a \(2\deg ^2\)  field of view (FoV) with a pixel scale of 0.55 arcec pix\(^{-1}\)  [2]}. The J-PLUS contains a twelve-passband filter system, including five broad (\(u, g, r, i, z\) ) and seven medium bands from 3000 to 9000 Å. [3]} illustrates the scientific goals and the observational and image reduction strategy of J-PLUS.
